Crowds estimated between 30,000 and 100,000 descended on Copenhagen to protest.
1My oppressors have been many from my youth, may Israel now say;
2My oppressors have been many from my youth, yet they have not prevailed against me.
3They have scourged me on my back; they have made long their oppression.
4Yahvah is righteous; he will cut apart the cord of the wicked.
5Let all those that hate Zion be confounded and turned back.
6Let them be as the grass on the house tops, which pulls out and withers when the wind strikes it,
7where the reaper does not fill his hand, nor he who binds sheaves his embrace.
8They who pass by do not say, The blessing of Yahvah be on you; we bless you in the name of Yahvah.
The timing for this Psalm begins around sunset on Friday night in Copenhagen. The crowds form overnight and have a large protest across Saturday. An estimated 1000 people were arrested.
The Psalm deals with general themes of oppression. The crowds were calling for more oppression in a vain attempt to end Global Warming. (Especially verses 1 through 3.)
The arrests made during this protest are seen in verses 5 and 6.
Verse 7 suggests they will attempt to reap something, but it will be like harvesting grass from a roof.
The final verse suggests these crowds are not acting in a way to bring a blessing from God.
